Mr Jeremy Lim, a spokesman for the Zeppelin and Co shop, also told The Straits Times that the two had "spent an intimate half hour chatting to customers as well as staff, and everyone was pleasantly surprised with how cordial they were and willing to engage in conversation, accepting feedback humbly and in turn sharing the inspiration for their work.

"We were greatly encouraged that international names took the time to talk to the customers of an audio shop and ask people for feedback about their music," added Mr Lim.

The two apparently visited Madame Tussauds Singapore as well, as seen in a cheeky video posted on Chou's official Instagram account on Wednesday (Sep 12), along with a caption in Mandarin comparing whose eyes -- JJ Lin or himself -- were bigger.
